After Recent update -- Suspend to Ram Button now Hibernates

I’ve got an IBM X22 laptop and after doing an update in the last few days the sleep button on my keyboard (Fn + f4) now puts the laptop into hibernate. There’s another button for hibernating and nothing happens when hit that one.

powersave -u

still has the desired effect though. Anyone having the same problem? Or have an idea how to fix it? I’m hoping it’s something silly…

I may be way off, but it’s possible its just a keyboard shortcut issue. What keycode is associated with that key?
Open a terminal, type


and then press the key and have a look at the output.
